What is IPv6? Learn about the IPv6 address of the Internet

Ipv6 is a very new concept for Internet users because it has not been applied much. However, this will be the technology of the future and will apply very much the same as the IPv4 we are using. newsoftwarelab will introduce you to IPv6

IP is considered your own address on the Internet so that you can communicate with the outside world, which is similar to sending a letter to a relative who needs a clear place of origin. Your IP range will include a string of numbers, converted into domain names for easier retrieval through domain name resolution (DNS)
Since a series of finite numbers is organized into a series of regular numbers, the number of IPv4 addresses is increasingly depleted, especially in the age of the Internet exploding and becoming universal. sea. The speed of Internet development so fast requires upgrading the IP system to meet the needs of the user. For that reason, IPv6 address was born.
What is IPv6?
The difference we can see most clearly between IPv4 and IPv6 is the length of the address.
For Ipv4
Ipv4 is using the current includes 32bit, consisting of 4 numbers separated by dots. For example:
Ipv4 vs ipv6
Each part of the Ipv4 range is called octets and has one byte of data
For IPv6
IPv6 includes 128bit, so the length of the IP will be larger, which is equivalent to the number of addresses generated from the 128bit set will be much larger.
Ipv6 addresses will be written in 8 groups, each with 4 hexadecimal numbers separated by a ":"
For example: 2001: 0260: 0000: 0010: 0000: 0000: 0000: 0001
Due to the large number of IPv6 addresses, it is often very time-consuming to remember or write down these addresses. For that reason, IPv6 has been conventionally abbreviated as follows:
- You can omit the number 0 to the left of each cluster
- A zero sequence can be reduced to a single zero
- A string with multiple blocks containing only zero can be replaced with a ":"
For example: IP address 2001: 0260: 0000: 0010: 0000: 0000: 0000: 0001 will be abbreviated to
2001: 260: 0: 10 :: 1
(":" Is only used once per IP address)
Typically, for a site that is assigned an IP address of in IPv4, the administrator will have to replace the complex and difficult IP address above with a clear domain name and resolve them with the DNS adapter. For example, http://taimienphi.vn
Interestingly, sometimes to access a site with a fixed port, you will need to have a clear port address and separated by a ":".
For example, if you want to access a site with IP port 80, you will need to type http: // in the address bar.
This obviously affects the deployment of IPv6 because blocks of IPv6 are usually separated by a ":" sign. The name resolution system will not distinguish between valid addresses if the ":" port is added: In the back.
To do this, if you want to access a website using IPv6 with a fixed gateway to access the service, you type in the form
Http: // [2001: 0260: 0000: 0000: 0000: 0000: 0000: 0001]: 80 /
Http: // [2001: 260: 0: 10 :: 1]: 80 /
This article introduces you to some information about IPv6, which differentiates the differences between IPv4 and IPv6. This concept will also be discussed a lot in the future. In addition, for each different network transmission, you should also set static IP address to protect the internet of your place or work, refer to how to set static ip address that we have introduced. .
